madVR - high quality video renderer (GPU assisted)

[Soukyuu]

Just played around with mpv and was wondering why all the videos were so laggy on pans even though no frames were dropped... Then remembered mpv does not have smooth motion. Scary, how fast one gets accustomed to some features and forgets they are even there.

Another friend of mine has hacked an nvidia card to transform it in a Quadro card with 10 bit output. So is it true? Our video card are really 10 bit output?

Thanks

you don't need a quadro or some thing special to output 10 bit every amd/nvidia card can do this with directx 10/11.
but madvr can't do this so this only harms the picture or at least doesn't help at all.
to output 10 bit on Directx 10/11 you need to disable aero or it automatic gets disabled.

rgb 8 bit (if fully supported) should result in a way better picture then 10 bit 4:2:2 YCbCr with the current stand of MadVR.

a quadro can output 10 bit opengl that's it and it can do this with dvi.

I have found that In november 2013 , Madshi wrote this :

"In any case, I think if 10bit is supported at all, it's likely to be with DX11, but not with DX9, and madVR currently uses DX9 for presentation. So supporting 10bit is not an easy thing to do with madVR. I might have to move presentation to DX11. And that means: Not anytime soon.

I would be interested in hearing whether NVidia and AMD really do support 10bit output properly. Here's a way you could test it, if you're interested: You could render a FullHD grayscale. Left most pixel black, right most pixel white (or the other way round). Calculate every pixel in between to be a 10bit intermediate step between black and white. Don't use dithering, just straight 10bit rounded results. Then display the same thing with 10bit and 8bit. If the 10bit result looks noticably smoother, 10bit output seems to be working. "

Now Madshi support dx11 for dithering , has changed something for 10 bit output too? Someone tried Madshi requests? Thank you

I'm 99.9% sure only Quadro can output 10-bit.

If there is Madshi madvr support , my real vw200 10 bit panel are just warming up the engine.

Quadro can do 10-bit in OpenGL, but any (NVIDIA) consumer card can do 10-bit through Direct3D full-screen, its just that nothing ever uses that.
Don't even need a registry hack or modded quadro drivers.

See here for official confirmation:
http://nvidia.custhelp.com/app/answe...a-geforce-gpus

madshi said that he might support this in the future, but he doesn't provide ETAs for his features, so all we can do is wait.

[James Freeman]

Can we test this with "Enhanced Video Renderer" that comes with MPC-HC (it supports 10-bit output)?
I use DisplayPort + Dell U2410 (supports 10-bit input with DP).

Although I'm still pretty sure no other Nvidia card except Quadro can do true 10-bit output.

BTW, it's interesting to see that even though its TDP is advertized as 60W, most boards are capped to 38.5W and you have to flash a modified BIOS in order to try uncapping it. It's measurable too. Makes you wonder why some manufacturers add a PCI-E power connector, maybe to be taken seriously.

Yep, the more I think about it the more I agree with you....we need a twice faster version of the 750Ti, I guess they take their time to release it as they currently own the performance-per-watt market and they wanna milk the cow without cannibalizing Kepler.

I recently saw a 29.97fps movie, what a relief to see smooth pans

They can whine all they want for 48fps but if movies were 29.97 this would already be a major breakthrough.

[DragonQ]

FWIW I'd have gotten an nVidia 750Ti if buying new. Seems to be easily the best card right now for non-hardcore gamers, who'd require a more heavy-duty GPU. The only reason I got a an R9 270 instead is because I got a great deal on a barely-used one.

I ordered an EVGA 750Ti Superclock and will be here sometime this week. I hope madVR will be able to handle the following on 720p24 sources on a 1920x1080p display...

Image Doubling: NNEDI luma doubling 32 neurons
Image Downscaling: Catmull-Rom AR LL
Chroma Upscaling: Jinc3 AR
Deband: Low/High
Dithering: ED1, colored noise, change every frame
SmoothMotion: Always (display is running at 60p)
3DLUT: Enabled

Currently, with a 650Ti on a 720p24 source, madVR can handle...

Image Doubling: NNEDI luma doubling 16 neurons
Image Downscaling: Catmull-Rom AR LL
Chroma Upscaling: Jinc3 AR
Deband: Low/High
Dithering: Ordered, colored noise, change every frame
SmoothMotion: Always (display is running at 60p)
3DLUT: Enabled

Sounds good, more feedback so I can avoid impulse purchases but FWIR it's barely as fast my 7850, efficiency drops once you overclock it & it gets hot too...even more so if you increase voltage and o/c it to 1.4Ghz.

BTW, is there a way we could set the number of queues in profiles please? Ideally I would like to have a profile for watching still pictures, I would use a renamed PotP .exe and would like to disable refresh rate rolling(as PotP's picture splitter forces 50Hz) & lower all queues to the minimum in order to avoid useless black frames. Watching pictures with mVR would become far more enjoyable

for 1080p24 bluray movies,

does chroma upscaling ( not chroma image doubling) nnedi3 32 netrons usefull or bc75ar is enough...most of the time i cannot see any difference, but i want not most of the time better, i want all time the best settings..( i cannot neutron64 for chroma upscaling, it causes dropped frames)

Well the point is that the 750 is efficient, not that it's fast.

While performance might be the same, it should be about 60% more efficient than a reference 7850 - but I would say that it's not worth replacing a card for efficiency reasons, only for performance ones.

Unless you need more performance now, I would wait for the higher-end Nvidia 8xx cards later this year, which should have similar efficiency but higher performance.

[leeperry]

Well, the only thing I'm afraid of the crazy summer heat on that o/c 7850 but a stock 750Ti will make feel frustrated(especially after madshi's latest update for AMD boards, brilliant! I can do 64X chroma + 256X luma on 576*340) and once overclocked they do get hot. My german's rusty but faster Maxwell's would appear to have been taped out and I gotta say that the MSI Twin Frozr 4 cooler looks very impressive(dual direct-touch heatpipe, giant fans, barely audible under load)...too bad it only comes with a 2y warranty. A $200ish faster TF4 750Ti sounds full of win

To some ppl, enough is never enough(and sometimes it's even placebo ^^)...it all depends on your display, your expectations, whether you are willing to substantially increase your electricity bill for NNEDI, but rest assured that OCD'ed ppl aren't necessarily happier(they keep chasing a few percents here and there in the desperate hope that they willl add up in the end) so if BC75AR does it for ya then more time & money for less frivolous activities, winning

[artins90]

With my 7950 I can handle luma image doubling nnedi3 with 32 neurons but only for 24 fps content, any video recorded at 30 fps or higher is too much for my GPU so I have to disable it manually when needed to avoid dropped frames. I would really appreciate a setting to automatically disable image doubling when the fps is higher than a set value.
I hate the fact that I'm almost able to run at 30 fps, the render time needed for 30fps is 0.33ms while my upscaled 720p videos take 0.36-0.38 ms to render I'm so close

I think you're going to be fine. With 720p25 I'm doing:
Image Doubling: NNEDI luma doubling 64 neurons
Image Downscaling: Catmull-Rom AR LL
Chroma Upscaling: Lanczos 4 AR
Deband: Low/High
Dithering: ED2, colored noise, change every frame
SmoothMotion: Disabled
3DLUT: None
Shader: Luma Sharpen post resize via mpc-hc

This is with +240 to the GPU, with a regular EVGA GTX 750 Ti. I'm even able to get 256 neurons with lower quality, 576x432 clips. 480p is just out of reach unfortunately, and I'm stuck with 128 luma neurons + 32 chroma doubling. With 29.97fps clips I'm stuck at 32 neurons, regardless of resolution. All in all I think it's a great card, and amazingly efficient.

[seiyafan]

Is Low/High the most popular setting for debanding?

[Mangix]

PSA: setting the flush settings to don't wait for everything results in fewer frame drops with NNEDI3 enabled.

edit: I just did a few more tests and found exclusive mode to be underwhelming. The upload and render queues were always low whereas windowed mode(both overlay and non) had queues that were relatively full(5-6 and maybe 2-3). This does result in occasional frame drops. No such issues with windowed modes. I thought exclusive mode was supposed to be better.

[Procrastinating]

AMD have released new drivers, I wonder if there has been any improvements?

That's what profiles are for as an example here is mine (I push my GPU to 90%+ for each and every one of these profiles):

if (srcHeight < 481) and (deintFps < 31) "SD 30fps"
elseif (srcHeight < 541) and (deintFps < 26) "1/2 HD"
elseif (srcHeight < 541) and (deintFps < 31) "1/2 HD 30fps"
elseif (srcHeight < 721) and (deintFps < 26) "720p24"
elseif (srcHeight < 721) and (deintFps < 31) "720p30"
elseif (srcHeight < 721) and (deintFps > 31) "720p60"
else "1080p24"

I can add new profiles if the content I watch requires it. Each profile only contains chroma upscaling, image doubling and dithering
